Wow. So how do Vega 64 GPUs function in small to medium size computer cases where they share a PSU, space, airflow, etc. with other components?
As much as I truly prefer Macs as laptops, if I needed both a laptop *and* and “pro” grade GPU (whatever that means... one that works?) I’m pretty sure I’d go with a reputable PC laptop and check off either the GTX 1070 or 1080 option. Because portability is the idea, right? All else equal, wouldn’t you rather be in front of a nice large monitor with a keyboard and mouse?
Honestly, how is Nvidia (not a company I necessarily like) able to fit a 1070 or 1080 into a laptop— and Mac users are spending over $1K on another waste paper basket that needs to be tethered to a “pro” grade outlet to provide any benefit? It’s extremely un-Apple, dude. Verrry un-Apple.

I must be missing something here.
